Infineon Technologies SCR Module, part number TD251N18KOFHPSA1, is a high-power semiconductor switching device designed for demanding industrial applications. This module features a 1.8 kV repetitive peak off-state voltage and a 410 A RMS on-state current rating. The internal configuration utilizes a series connection of an SCR and a diode, providing robust power control capabilities. With a maximum on-state voltage of 250 A (average) and a non-repetitive surge current of 9100 A at 50 Hz, it is engineered for high-impact switching events.
The TD251N18KOFHPSA1 operates within a temperature range of -40°C to 125°C and employs chassis mounting for efficient heat dissipation. Key trigger characteristics include a maximum gate trigger current (Igt) of 200 mA and a gate trigger voltage (Vgt) of 2 V. The holding current (Ih) is rated at a maximum of 300 mA. This component is commonly found in power control systems, motor drives, and high-voltage power supplies across various industrial sectors. The module is supplied in tray packaging.
